feriados.io vs Calendarific
Both return holiday data. The difference is what you can do with it: Calendarific gives you a list of holidays. feriados.io gives you a list of holidays plus the endpoints to calculate business days, add deadlines, and count working days per country.
The core difference
Calendarific is a holiday data API — it tells you what days are holidays in 230+ countries. feriados.io is a business calendar engine — it tells you what days are holidays, and also calculates deadlines, counts business days between dates, and validates payment dates. If your use case requires date arithmetic (payroll, SLAs, delivery dates, billing cycles), Calendarific requires you to build that logic yourself on top of their data.

When to choose each
- ✓ You need to add or subtract business days (delivery dates, payment deadlines, SLAs)
- ✓ You're building for Latin America specifically
- ✓ Your app processes payments, payroll, or logistics in LATAM
- ✓ You need to know if a specific date is a business day before running logic
- ✓ You want decree alerts when Argentina adds a new puente
- ✓ You need the Chile irrenunciable distinction in your HR or payroll system
- → You need holiday data for countries outside Latin America
- → You only need to display a list of holidays — no date arithmetic
- → You're building a calendar UI that just shows holidays visually
- → You need holiday data in multiple languages for a global product
- → You need state or region-level holidays across many countries
What you'd have to build yourself with Calendarific
Calendarific returns holiday lists. If you need to add 5 business days to a date in Colombia, you'd need to fetch the holidays, implement the Ley Emiliani logic, and build the date arithmetic yourself. feriados.io does it in one call.
// 1. Fetch holidays from Calendarific
const holidays = await calendarific.holidays({
country: "CO", year: 2026
});
// 2. Implement Ley Emiliani shift logic yourself
const shifted = applyLeyEmiliani(holidays); // ← you write this
// 3. Implement business day counter yourself
function addBusinessDays(date, days, holidays) {
// ← you write this too
}
// 4. Finally get your answer
const result = addBusinessDays(startDate, 5, shifted); // One API call — done
const res = await fetch(
"https://api.feriados.io/v1/CO" +
"/business-days/add" +
"?date=2026-01-07&days=5",
{ headers: {
Authorization: `Bearer ${KEY}`
}}
);
const { data } = await res.json();
// data.result_date → "2026-01-14"
